A floatless relay is an electronic device used in industrial control systems to monitor and control electrical equipment. It is designed to provide a low-cost, reliable alternative to traditional electromechanical relays. Unlike traditional relays, which rely on mechanical contacts to switch electrical currents on and off, floatless relays use solid-state components to perform the same function.
Floatless relays are commonly used in applications where electrical equipment needs to be switched on and off based on the level of a liquid or gas in a tank or vessel. They can detect the level of the fluid using various sensors such as ultrasonic sensors, capacitive sensors, or pressure sensors, and then trigger a switching action based on pre-programmed logic. This allows for precise control of the equipment and can help prevent overfilling or underfilling of tanks.
Overall, floatless relays offer several advantages over traditional relays, including faster response times, longer life expectancy, and higher reliability.
